travail d'une force:
Wab(F):F(N)*AB(mètre)*cos (x)
Ec(joule)=1/2*m(kg)*v2(au carré en m/s)
Epp=m*g*z
Em=Ec+Epp 
Variation de Epp= -W(f)
Variation Ec=Ecb-Eca= somme Wab(F)
Variation Em =VariationEc = variationEpp
ou chute libre = 0

trouver la hauteur :
z=Em/m*g

trouver la vitesse :
  v=racine carré m*g*h*2/m
v=racine carré 2*g*h
